Exit Pop Up that is Google Adwords Friendly

I am interested in creating a interstitial exit pop. What I mean is I need an exit pop that appears if someone does not buy, tries to close out the window, or pushes anything on their task bar (such as the back button). This should really be a pop over not a pop up. Google Adwords does not allow the use of pop-ups but they do allow 'interstitial' pop-overs if they don't 'pop' open a new window. Therefore, it must comply with their rules. Furthermore, it should beat pop-up blockers and not get detected by them if this is the case. Meaning, if they do not truly cause a 'pop-up' they are really just code placed within the HTML. So if the user doesn't buy or hits the back button or closes the window, the window should not close but should bring up this 'interstitial' pop over that can say what I need it to say. Furthermore, what it creates should look great and should be easily changeable. The bottom line is, I have a sales page that converts well. However, if the user doesn't buy, I want them to be able to have another offer only after I am sure they are leaving or aren't buying.
